Embodiment 1

[0074] This embodiment provides a method for preparing a photochromic ceramic tile with a decorative pattern, comprising:

[0075] Step 11, pressing the blank and placing it in a roller kiln for drying to obtain a ceramic brick body;

[0076] Step 12, applying an underglaze on the ceramic tile body to obtain an underglaze layer;

[0077] Step 13, applying pattern decoration glaze ink on the bottom glaze layer to obtain a pattern decoration layer;

[0078] Step 14, applying a color-changing decorative glaze on all or part of the decorative pattern of the pattern decoration layer to obtain a color-changing decorative glaze layer;

[0079] Step 15, applying a transparent glaze on the color-changing decorative glaze layer to obtain a transparent protective glaze layer;

[0080] Step 16, firing in a kiln to obtain ceramic tiles that change color with light.

[0081] Further, the chemical composition of the photochromic glaze is in mass percent, including:

[0082] SiO 2 41.6~...

Embodiment 2

[0102] This embodiment provides a method for preparing photochromic ceramic tiles with decorative patterns, which differs from the above-mentioned first embodiment in that the chemical composition of the photochromic glaze is expressed in mass percent, specifically including: SiO 2 43.59%, Al 2 o 3 18.44%, Fe 2 o 3 0.14%, CaO 6.43%, MgO 6.88%, Na 2 O 3.03%, K 2 O 0.34%, ZnO 7.42%, TiO 2 0.11%, B 2 o 3 4.6%, BaO 8.2%, CuO 0.02%, AgBr 0.8%.

Embodiment 3

[0104] This embodiment provides a method for preparing photochromic ceramic tiles with a decorative pattern, which is different from the first or second embodiment above in that the patterned decorative layer and the color-changing decorative layer are applied by a parasitic screen printing process; The transparent glaze layer is applied by a bell jar glazing process.

[0105] Further, in this embodiment, the specific gravity of the glaze slurry of the color-changing decorative glaze is 1.50; the mesh number of the screen used in the alignment screen printing is 80 mesh.

[0106] Furthermore, in this embodiment, the glaze fineness of the transparent glaze is 3.2-3.8% on a 325-mesh sieve; the viscosity of the glaze slurry is 27-34s as measured by a Marsh funnel; the specific gravity of the glaze slurry is 1.68-1.75; Glazing amount: 220~320g / m 2 .

Abstract

The invention discloses a decorative pattern photochromic ceramic tile and a preparation method thereof. The method comprises the following steps: A, press forming of a blank and drying in a roller kiln to obtain a ceramic tile blank; B, applying a bottom glaze on that ceramic tile blank body to obtain a bottom glaze layer; C, applying pattern decorative glaze ink on that bottom glaze layer to obtain a pattern decorative layer; D, applying a discolored decorative glaze on all or part of that decorative pattern of the pattern decorative layer to obtain a discolored decorative glaze layer; E, applying a transparent glaze on that discolored decorative glaze lay to obtain a transparent protective glaze layer; F, firing and molding in a kiln to obtain the photochromic ceramic tile. By applyingthe bottom glaze, the color rendering effect of the decorative ink is improved. By applying the discolored decorative glaze on the whole or part of the decorative pattern on the decorative layer of the pattern, the color of the decorative pattern photochromic ceramic tile changes with the light after firing, and the decorative effect and the aesthetic effect are improved. By applying transparent glaze, the coloring effect is improved and the surface of ceramic tile is protected.

Description

technical field [0001] The invention relates to the field of building ceramics production, in particular to a photochromic ceramic tile with a decorative pattern and a preparation method thereof. Background technique [0002] Ceramic tiles of architectural ceramics have always been an important decorative material for home furnishing and engineering decoration. It has a variety of excellent physical and chemical properties, in addition to pollution resistance, wear resistance, high hardness, no fading, no radioactive pollution, and good ease of cleaning. , especially because of its many patterns, rich colors, superior surface texture and variety, and bright and beautiful decorative effects, it has become the favor of consumers. With the progress and development of the research and development of architectural ceramic tiles and production technology, the decorative technology of ceramic tiles is becoming more and more mature, the surface patterns and colors are becoming more ...
